5-24 Why must air compressor oil have good oxidation stability? What is the evaluation method?

Air compressor oil uses low-viscosity, deeply refined oils to avoid carbon-prone substances. Evaluation follows GB/T 12709-1991 and GB/T 12581-2006 for oxidation and aging stability, enhancing product reliability.

Butiran Kes

Answer: Air compressor oil with poor antioxidant stability is prone to produce sludge and carbon deposits. Air compressor oil with poor thermal stability is prone to decompose to produce light hydrocarbons and carbon dust, which are the main causes of air compressor oil explosion.

The substances that are prone to carbon deposits in oil products are mainly colloids, asphalt and polycyclic aromatic polymers, which can be removed by deep refining. Therefore, air compressor oil generally uses low-viscosity, deeply refined oils without heavy bright oil as base oils, and avoids ash additives as much as possible to improve the oxidation stability and stability of oil products.

The evaluation method is GB/T 12709-1991 "Determination of aging characteristics of lubricating oils" and GB/T 12581-2006 "Determination of oxidation characteristics of mineral oils with inhibitors".

However, those with sealed components, including motors, controllers, and connectors, can also be operated outdoors. Performance IC forklifts tend to be utilized in heavy-duty applications, such as brick and lumber yards, where larger capacity and performance is required to move the heavy loads.
